THE SOLAR RADIATION AT SHANGHAT CITY AND ITS RELATION TO THE INTENSITY OF THE URBAN HEAT ISLAND
上海城市太阳辐射与热岛强度

In order to clarify the effect of solar radiation on the intensity of urban heat island, we survey the daily data in the year of 1984 of Xinzhuang(rural) and Longhua(urban) and use 154 days as regression samples- The regrassion equation (see Eq. 1) shows that the direct solar radiation has a. positive effect on the intensity of the Shanghai urban heat island but the wind velocity and the cloudiness have a negative effect on it. By using the records provided by satellites and the simultaneous observational data of solar radiation and relative meteorological factors, we analyse several typical cases of Shanghai urban heat island in different seasons.
